Hybrid Tea Rose plant named ‘Scholtec’

ABSTRACT

A distinctive cultivar of Hybrid Tea Rose plant named ‘Scholtec’, characterized by its dark green-colored leaves; vigorous growth habit; long and strong flowering stems; large mauve-colored flowers; high yield of cut flowering stems; and good postproduction longevity.

Botanical classification/cultivar designation: Rosa hybrida cultivarScholtec.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of HybridTea Rose plant, botanically known as Rosa hybrida, and hereinafterreferred to by the cultivar name Scholtec.

The new cultivar is a product of a planned breeding program conducted bythe Inventor in De Kwakel, The Netherlands. The objective of thebreeding program was to develop new cut Rose cultivars with a high yieldof cut flowering stems, attractive flower color, long and strong stems,dark green leaves and good postproduction longevity.

The new cultivar originated from a cross made by the Inventor in 1999 oftwo unnamed proprietary selections, not patented. The cultivar Scholtecwas discovered and selected by the Inventor as a flowering plant withinthe progeny of the stated cross in a controlled environment in DeKwakel, The Netherlands. The new cultivar differs primarily from plantsof the unnamed proprietary selections in flower color.

Asexual reproduction of the new cultivar by cuttings taken at De Kwakel,The Netherlands, since 2000, has shown that the unique features of thenew cultivar are stable and reproduced true to type in successivegenerations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Scholtec’. These characteristics incombination distinguish the new Hybrid Tea Rose as a new and distinctcultivar:

1. Dark green-colored leaves.

2. Vigorous growth habit.

3. Long and strong flowering stems.

4. Large mauve-colored flowers.

5. High yield of cut flowering stems.

6. Good postproduction longevity.

Plants of the new Hybrid Tea Rose can be compared to plants of thecultivar Schrenat, disclosed in U.S. Plant patent application Ser. No10/109,950. In side-by-side comparisons conducted in De Kwakel, TheNetherlands, plants of the new Hybrid Tea Rose differed from plants ofthe cultivar Schrenat in the following characteristics:

1. Plants of the new Hybrid Tea Rose were taller and broader than plantsof the cultivar Schrenat.

2. Flowers of plants of the new Hybrid Tea Rose were mauve in colorwhereas flowers of plants of the cultivar Schrenat were pink in color.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Hybrid Tea Rose have not been observed under allpossible environmental conditions. The phenotype may vary significantlywith variations in environment such as temperature and light without,however, any variance in genotype.

The aforementioned photographs, following observations and measurementsdescribe plants grown in De Kwakel, The Netherlands, in glass-coveredgreenhouses with an average day temperature of 19° C. and an averagenight temperature of 15° C. Plants used for the photographs and thedescription were about five months old.
